GAUGE STOP FOR GLASS TABLES Oliver M. Itaya, Cleveland, Ohio, assignor to The F. C. Russell Company, Cleveland, Ohio, a corporation of Ohio Application November 5, 1947, Serial No. 784,191

6 Claims. (Cl. 33-18) This invention relates to gauge stops, and more particularly to such stops for use on glass processing or cutting tables.

Tables for supporting glass sheets while the latter are scored or cut to size customarily include guide rails or fences against which the edges of glass sheets are abutted and along which the glass is measured. It is also conventional to mark permanent scales on glass cutting or processing tables, particularly along the .guide rail or fence, to facilitate measurement of the sheet being processed. When glass sheets are to be cut to uniform size in large quant-ities a stop or indexing device mounted on the guide rail or fence serves to locate glass sheets on the processing table'in predetermined position. The present invention is directed to the general improvement of vgauge stops for glass processing tables and the like, it being one of the principal objects of the invention to provide a gauge stop which normally is movable to different positions along a supporting Vguide rail or fence and which is readily displaced to clear the edge of a glass sheet so that the latter can be shifted along the guide rail without altering or interfering with the setting of the stop on the guide rail.

Another object of the invention is to provide, in combination with a glass processing table, a gauge stop having a glass contacting element that, upon movement thereagainst of the edge of a glass sheet, is movable in a direction transverse to the plane of the glass so as to clear the glass for movement past the gauge stop. More specically, and as a preferential arrangement, the invention aims to provide a gauge stop of the character mentioned which has a glass contacting element pivotally mounted for displacement out of the path of a. supported glass sheet. The

glass contacting element is supported for move-- ment either upwardly or downwardly into and out of the path of a glass sheet or plate supported on the processing table, a suitable arrangement being one in which the element is located on the end of agpivoted arm so as to rest by gravity on the glass supporting structure of the table or on the topof a glass sheet or plate interposed between the supporting structure and the glass contacting element of the gauge. The arm is so pivoted and the element is so shaped that when the glass is moved against the` element in one direction the element rides overthe edge'oi the glass so as to be supported on the latter, permitting the glass to be moved about over the supporting table without interference vor hindrance by the gauge stop. When the edge of the glass sheet 'or plate is moved against glass contacting element in another direction, the element acts as a stop to limit the glass movement thereby serving to locate the glass in predetermined position on the table.

arrangements of parts which will become apparent as the following description of a suitable embodiment proceeds. This description is made inl connection with the accompanying drawings forming a part of this specification and in which like parts are indicated by the same numerals of reference in both views.

' Fig. 2 is a view, partly in section and with parts broken away, taken substantially on the line indicated at 2-2 of Fig. l.

The gauge stop is shown mounted on the guide rail of a structure of the type disclosed in oopending application for United States patent Serial No. 784,267 filed November 5, 1947, now Patent No. 2,578,919 granted December 18, 1951, and entitled Glass Processing Table. Parts described in the application referred to are identifled in the drawings of the present invention by the same numerals of reference. f

The Work table or bench on which glass sheets are processed or cut has a top l of wooden planks or plywood. A niunber of sheet metal tubes 5 are disposedacross the top of the table.' The tubular supports are arranged in pairs, one such pair being shown in the drawings, and they each have upstanding flanges I0 formed by reverselybent portions of the metal of the tubes. Reverse bends I l of the several tube flanges are disposed to lie in substantially a common plane parallel to the table top for supporting contact with the underside of a glass sheet G to be cut or processed. The reversely bent flanges Il provide smooth straight surfaces for contacting the undersides of the glass sheets and the edges of the vupstanding flanges have a wiping action which removes from the glass grit and other for- 'Other objects and advantages of the invention G0 relate to'certain details of construction and eign particles which might otherwise scratch the glass sheet. The removed grit and particles drop down into the spaces between the flanges.

vAlong one end of the table, but not illustrated in the drawings, is a bed bar and cutting guide used in cutting or trimming the glass sheets. Along a side edge of the table, at or other suitable angle to the bed bar and glass cutting guide, is a guide fence or rail 3U formed of a strip.;v of sheet metal bent or rolled to approximately?- T-shape in cross section and supported on a wooden spacer 3l. The rail 30 and the spacer 3| are secured to the table top l by screws, not shown. The guide rail 30 extends above the level .of the glass supporting reverse bends Vof the flanges I0 and bottom flange 33 of the guide fence abuts and parallels `one of the glass supporting tubes 5. f

A sheet of glass being processed on the table is .brought edgewise into abutment with the guide fence 30 so as to properly orient the glass. To locate the glass for cutting "to` predetermined length an edge thereof is brought into engage'- ment with a guide stop mounted on the rail 30. The present invention is particularly concerned with the construction and operationof th vguide stop. This device comprises a cast metal 4body member 36 which may alsof'be A Ina'chined""frorr`1a solid block. A transverse slot 31 adrss`tl bottoni of the body receives and has a running t on the guide rail 30 so that the stop can Vbe moved to different positions along the rail. A thumb screw 38, threaded through the stop body 36,` may be made to bear against the rail 30 to clamp the stop in adjusted'position; A channel in the top (if the bodymember 36 is disposed transversely t fthe vslot 431 and receives: one end f an Lfsneed arm 39. 'walls 42` of 'the channel having suding'engagement with the anni@ guide the latter. The'ia'rm is pivoted for up' and down movement on a pin 40 secured inthe stop body 3S and is engageable with the bottom of the channel to liiit'downward movementof the arm. """The arm 39V constitutes part of a glass engag. ingelefnent'or assembly Which`also includes'a roller 4|' mounted on the bottoinend of the depending portion'of thefarm.' M'ltfla'nged bushing orv ferrule 44' is' received by a press or shrink t within a central bore 45 "of the roller 4| and is rotatable on a shouldered cap"screvvI '46 threaded in't the loweend of tlie`depfer'1-dingd portion of the arm. The bushing 44 is of 'less' axial lengthth'an the roller bore 45 so that the head of the tiap' screw is recessed within the bore and end surface 41 of the roller is unobstructed. V

As shown in Fig. 2 the roller projects below bottom end 4B of the arm 3Q providing al clear-'-v ance 49 between the arm and the upperedge'ot the glass supporting flange I on which the roller 4 rests b y gravity. The width of the base flange 33 of the guide rail 3 0 such that the upstandf ing glass supporting flange I0 of the glass'sl'ip.- porting tube abutted against the rail flange is diefV posed directly under the rotational axis of the roller 4I- In adjusting the guide stop on the rail 3Q the body 3,6 of the stop is slid along the rail to a pro-p sition in which the distance from the face 41 o f the roller to the cutting guide of the glass process table represents the desired dimension at which the glass is to be cut. The thumb screw 38 is then tightened against the rail 30 to lock the gauge stop in position. Thereafter a glass sheet G brought against the rail guide 30 to the left of the gauge stop, as viewed in Eig. 2, .and then moved in th-e direction of arrow 50 into abut.- ment with the face 41 of the roller 4| is located on the processing table in the desired position for cutting or scoring.

When it is desired to cut a glass sheet to a dimension longer than that for. which the gauge. stop is set, the glass sheet is rst moved in the measure a glass sheet moved against the roller as in Fig. 2. t

` Curved periphery 52 of the roller provides an inclined surface which is disposed at an acute angle to the plane of a sheet of glass supported on the reverse bends I of the table flanges I0. This inclined surface enables the glass contacting element comprising the arm 39 and the roller 4| to ride ove'ti'ie" edge of a sheet of glass moved against the roller` in the direction of the arrow 5| (Fig. 1). Although the inclined surface which rides over the edge of the glass sheet is provided bythe periphery of a rotatable roller, a similar although less efficient arrangement is providedl by a non-rotating glass contacting element having a bottom surface curved or inclined Vat an acute angle to the plane of the glass'. Forexam'plle,4 the curved or rounded bottom of the depending portion of the arm 3'9 maybe used Without'the 'roller In the commercial or large scale production of glass lights out to predetermined dimensions from large sheets or plates, as, for example, in'the manufacture of windows'and doors, a number of the gauge stops of the present invention are mounted along the guide rail 30 at spaced intervals corresponding to the desired distances from the cutter guide bar. A glass sheet to be v(uit isV thenbrought into abutment ywith the guide rail 3|);l passing under the rollers of oneI or more of -the guide Vstops and 'being'brought' into edgewise abutment of the roller of the particular gauge stop that is to determine the'd'imensin of the cut to be made. Thus aglass processing` or cutting table can be equipped to facilitate the cutting of glass lights of various sizes without any necessityfor' the operator to individually scale the y dimension of each'cut to be made. The only requirement is that the operator move the glass sheet into edgew'ise abutment with the sideface 41 'ofthe proper gauge stop, the other gauge stops intervening between the measuring gauge stop and the cutter guide bar being elevated or raised out of'position'as the glass sheet is moved laterally into abutment with the guide rail 30.

The principles'of the present invention may be utilized in various ways, numerous modications and alterations being contemplated,substitution of'partsand changes 4in construction being re, sorted to asdesi'red, it being understood that the embodiment Ishownin the drawings and described above is given merely' for purposes of explanation and illustrationv without intending to limit the i scope of the'claims to the specific details disclosed.
